The solution of this problem consists in passing the process in a fluidized bed. However, the key issue of this solution is the problem of entrainment of solid material. Among feasible ways of the fluid bed hydrodynamics creation is a sound waves transmission through a solid granular material. A visual study on the fluid bed hydrodynamics creation with sound waves was conducted. The estimation of the impact of the trajectory of the particles on the thermophysical properties of the fluidized system was determined. The exploitation of sound waves should increase the intensity of heat exchange inside and between the solid and gas phases. Reactor design scheme for pyrocarbon coatings creation was developed. This scheme implies a small amount of material to be treated. The results obtained can be subsequently applied in the process of developing new fluidized bed apparatus, when the usage of a gas or a liquid as a fluidizing agent is technically impossible (or insufficiently). The prospects for further research include homogenization of the agglomerate layer by means of sound waves.

The proper technologies of combustion the wet inflammable mixtures are considered for the cases of using the water vapour pump (WVP), Maisotsenko cycle (M-cycle) and suitable facilities along with the cases of operation the combined systems with heat recovery due transfer the water vapour energy to working medium (combustion products). Both environmental and power advantages of the systems of «wet combustion» have been demonstrated accordingly data collected in some earlier researches. The results of experimental researches of burning process under conditions of input the water vapour into the gas–air mixture to be supplied for combustion are presented in the paper in frame of consideration the results of own authors’ tests. Given information concerning the investigation of environmental consequences of impact the water vapour within the inflammable mixture on nitrogen oxides NOx value in combustion products ([NOx] concentration) has been generalized. The techniques of experimental researches, the design of firing rig and instrumentation, used in the tests have been described. The distinction of ignition the natural gas-air mixture and of stable flame maintenance for case of free vertical flame operation have been evaluated in dependence on inflammable mixture’s composition along with studying of impact a moisture content — H2O concentration in initial gas-air mixture. Comparative evaluations of NO value within an open flame in dependence on temperature and on composition of initial natural gas — air mixture (ratio «air : gas») have been carried out. An opportunity of two-times reduction of maximum NOmax concentration within a flame by initial gas-air mixture enrichment with water vapour has been proven.

There was a significant decrease (up to 40 %) in the amount of wastes belonging to the hazard Classes I–IV as well as almost 40 times reduction in waste products of the hazard Class III. The largest amount of waste products of the hazard Classes I–IV was formed in Popilnia district, Andrushivka district and Zhytomyr. The smallest amount of these waste products was found in Pulyny, Brusyliv and Baranivka districts. The highest amount of available waste products was registered in Zhytomyr, in Korosten and Ovruch districts respectively. Berdychiv, Malyn and Brusyliv districts were characterized as those ones generating the least amount of waste products. The waste products of mining industry and wastes of organic nature, videlicet wood waste, plant and animal waste account for 28 % of all the wastes generated for the period of 2016. Household wastes, other mineral wastes, and dead rock account for 22 %, 21 % and 16 % respectively. The lack of properly functioning infrastructure (first of all, the system of separate collection) causes annual losses of million tons of valuable resources contained in waste products. The simultaneous need of domestic processing enterprises for such raw materials is solved nowadays by means of purchasing such recyclable materials from other countries. The issue of further implementation of low-waste technologies as well as the improvement of regulatory and legal support in the field of waste management need urgent solving.

But the sludge use is quite problematic due to its high humidity and ash content. To reduce the moisture of the initial mass of the sludge, it is recommended to add dry finely dispersed biomass (saw dust, chopped straw). To conduct the research, we selected the long-term storage sludge samples of Bortnichi Activate Sludge Plant of Kiev city and the fresh sludge of the Lvov city purification facilities to produce the granules of 6 mm in diameter. The gaseous conversion of the granules was completed in the two stages according to the «backward heat wave» technology. As it has been established, the coke ash residue accounting for 53–63 % of the output sinters at the temperature of above 700 °С. The research has identified the gaseous conversion parameters, the composition and the combustion heat of the fuel gas. The recommendations pertaining to use of the fuel gas and the coke ash residue have been designed. Accordingly, the research conducted hereunder has discovered the possibility of full and partial gaseous conversion of the sludge granules using the air blast.
